摘要
明确了二级系统给水p H值约为7.75时系统透盐率达到最低值;论证了对于不同透盐率水平元件,若将较低透盐率元件用于二级系统而较高透盐率元件用于一级系统则全系统透盐率较低;讨论了调换一、二级系统元件的方式即形成系统元件的优化组合,以使全系统产水水质相应提高的工艺措施。
The minimum salt penetration rate could obtain when pH was 7. 75 in secondary system. The components with low penetration rate were used in secondary system and the components with high penetration rate were applied in first system, thus the penetration rate in the whole system was low. The exchange method of first and secondary system components was discussed. In result, the optimal combination of system components was formed, and process measures were adopted in order to improve the water production quality in the whole system.
